ThumbGate
Active·★ 29·MIT·Updated 2026-10-21
ThumbGate is a safety net for vibe coding. It captures thumbs-down feedback, auto-generates prevention rules, and pre-action gates physically block the agent before it repeats a known mistake. It works with Claude Code, Cursor, Codex, Gemini, Amp, OpenCode, and any MCP-compatible agent, providing a reliability layer without an extra orchestrator.
